puresound 2A3 upgrade to?

[the_doc735]

Hi

I've got the 2A3 (from Guy).

Can anyone suggest a suitable upgrade please?

I am currently looking at a ARION NEMESIS 300B for example?

Jadis? Audio research? McIntosh? Ayon? Wavac? Art Audio? Border Patrol? Viva? Ear? Pathos?

OR just upgrade the '2A3'?

:scratch:

Long Dog Audio 300b. Some of the most advanced regulation in any amp available today, and it really shows in the sound. Nick doesn't post here, but I can put you in touch. He's not a million miles away from you in Halifax, would be easy enough to arrange a demo.

Seriously, the best 300b amp I've ever heard. Not a shill, just my opinion. Nick is a friend, but I've nothing to gain from the recommendation. Give one a listen and decide for yourself.

Pure, blatant advertising but I have a Pathos Logos II with Hi-Dac going for £2795 and an EAR 899 incoming soon for notta lot.

How about a Border Patrol psu upgrade for the 2a3 amp?

I already asked Guy about that and he doesn't think it is anywhere near as important as it is for his A30. He gave a techy explanation for this that I can't replicate.

"In principle, the BP supply is a good thing although perhaps more for a Single Ended type amplifier which are generally more dependent on the quality of their power supply & which in many instances is under specified in most commercially made SET amps. It's less critical for a push-pull amp like the 2A3".

That's interesting but I must say I used to have 2nd audio mono amps, these were 2a3 push pull and although I needed two psu's the improvement was fundamental, quite impressive control in the bass, the 2nd audio as standard sound loose and flabby in the bass and can get congested, still unless you try it or hear it first you'll never know.

there's always chinese linear power supplies that are cheaper than border patrol?

Chinese linear psu, not familiar with those but I'd be very cautious about anything Chinese with known voltage issues.

funnily enough i tried to find guy on one of the forums but he seems to have dropped off the planet !!

very interested in how you get on . presumably you have seen the firebottle/monoblocks set up have you ?

should be OK if it genuinely has the correct volts and amps?

Guy occasionally decides to answer emails (sometimes). No, I haven't seen the firebottle/monoblocks actually.

[the_doc735]

The 2A3 Puresound doesn't seem to have any exotic components on board. Mine has OEM trade Solen and panasonic caps that cost a couple of quid each. Don't know about the resistors? From the emails I get the impression that Guy isn't into wasting money un-necessarily on expensive components.

i think its 500 quid at least for trade on the wam so i guess thats why he is not on .

[hifinutt]

It's not in his "official" line up, but he's made them for folk who have asked.

Paul,
another +1 for Nick's 300B amp.

Big testament to the guy (aside from knowing him personally, hence knowing He's forgotten more about valve amp design than a lot of folk actually know) but I genuinely could not afford to improve upon the amp he built for me, even if it were possible which even as a layman I kinda doubt.

Having 'seen the light' and discovered valve amps (I'll never go back) Nick's amp is the best I've ever heard, never mind owned.
Recently went 'full bhuna' valve wise and swapped out the good but entry level 300B valves Nick supplied with the amp to something a whole heap of better, and the amp showed exactly what the valves brought to the table.

As Ali said, the power regulations better than anything you'd find commercially and as you go up the ladder you learn that power is everything.

Contact Nick.
Seriously.
